On certain issues I tend to defer to Soxprospects take more than anyone. Especially on any baseball player outside of the top 50. I'm not saying they have superior scouting, they do not, but they do have more eyes on our players than anyone else. I've seen them ring the bells on guys all the time being overhyped and their fears materialized. For example, they were much lower on Lars Anderson than the national media was and they were proven correct, as they were to date with Jurran Duran as well. The opposite is true, they thought Xander Bogaerts was a high-ceiling future all-star 2 years before he made any top 100 lists (much in the mold of Bleis now).
They seem to think Rafaela is being overhyped now. They still think he can be a stud, and an allstar if the bat develops, but they seem to have some concerns about his hit tool.
At the very least, this should have anyone from thinking he's going to break through to the big leagues next year, or even be a staple in the lineup by 2024. He may end up just being a good 4th outfielder. I like him, but the hit tool seems to be an issue.
